TYPE- -WRITER CUSHION.

SPECIFICATION forming part of Letters Patent No. 776,251, dated November 29, 1904.

Application filed April 15, 1903.

To all whom it Wwty concern:

Be it known that I, ELBERT V. MENDEN- HALL, a citizen of the United States, residing at 1224 VVrightwood avenue, in the city of Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Type \Vriter Cushions, of which the following, when taken in connection with the drawings and reference-letters thereon, forming a part thereof, is a full and complete description.

The invention relates to improvements in cushions for type-writing machines; and the object thereof is to produce a cushion which will effectually destroy or muffle the noise of a manually-operated machine caused by its being in contact with a cabinet or desk and at the same time produce a cushion the effectiveness of which will not depend upon any particular shape. I am aware that a matting has been used for this purpose; but in practical use it is found that the weight of the machine forces the foot thereof into the mat and gradually causes it to become thinner and harder and destroys the mufiling power thereof.

Figure 1 is aview in perspective of the cushion embodying the invention. Fig. 2 shows type-writer cushions attached to a type-Writing machine.

Should the machine be attached to a dropcabinet in order to completely muflie the sound, the cushionmay be perforated and placed between the cabinet and the head of the bolt, as shown in Fig. 3.

A, Fig. 1, is a disk made of iron or other practically rigid material about three inches in diameter.

B, Fig. 1, is a piece of felt or other fibrous Serial No. 152,816. (No model!) material having practically the same diameter as the disk. a and 6 are holes. in such disk through which a thread is passed, attaching the felt to the under side of said disk.

0 represents clamps or means whereby the disk may be attached to a foot of a type-writing machine, as shown in Fig. 2.

The disk should be rigid, so that the weight of a machine applied to it would not cause it to give, but would transmit the pressure to the felt at every point on its surface, thus increasing the surface of contact thereof.

I prefer to have the cushion made of felt of about one-half inch in thickess; but other fibrous materials may be used.

It is not necessary that the disk or felt he of the exact size or shape as shown in the drawings provided they are, however, sufficiently large to distribute such pressure of the machine over a large enough area to produce the desired muffled effect.

In application one cushion is placed under each foot of the machine.

A device by which the noise created by type writersa nd other manual ly-operatcd machines may be diffused and deadened, consisting of a flat, rigid disk, attached to and placed upon a thick layer of felt or other fibrous material, means for loosely connecting said disk to said layer and means for connectingsaid disk to the foot of a type-writing or other manuallyoperated machine, substantially as and for the purpose set forth.
